Computer vulnerability evaluation using fault tree analysis

Abstract

For analyzing computer system security, the system visitor could be classified into five kinds by his privilege to access system resource, and presented the model base on privilege escalation. The attacker can enhance his privilege by exploiting vulnerability, according to distribution of vulnerabilities privilege set, we could construct fault tree to reflect distinctly potential attack path, and so this method could quantificational express security state at different security policy via analyzing fault tree. © Springer-Verlag Berlin Heidelberg 2005.
